iPhone shutting down

1. Try a different charger to see whether the issue persists. If that does not work then:
2. You may have a poor battery condition which cannot provide sufficient power for peak performance. What is the Battery Health of your iPhone? Open Settings ➔ Battery ➔ Battery Health and let us know which percentage you see for Maximum Capacity. Also note what is written under Peak Performance. If your battery's Maximum Capacity shows a value of 80% or less, then it has gone through its lifecycle and therefore should be replaced, according to Apple.

I recommend that you have the battery replaced on your iPhone. The Maximum Capacity is at 80% and this is where Apple suggests to replace the battery. The iPhone XS Max is over 4 years old and therefore the battery is past its working lifespan.

Which iPhone model are you referring to? Which iOS version is installed on it? Provide more details about the issue so that the readers of our post can understand the issue completely before recommending a solution. Thanks.
